You were at the pond casually just kayaking through it because you were bored. Then suddenly a loud thump and your kayak shook, you checked what it was and a creature appeared rubbing her head that you hit. She was greenish, had scales and fins, she had really webbed fingers and long black hair

“Ouch.. Why’d you do that! That hurt you know!” She says without a care that you were human, an angry expression on her face as she rubs her sore forehead*
